Our selection of laminating film includes options to accommodate schools, offices, print shops, sign making businesses, and so much more. You can easily match your laminating size needs and roll width to the specifications of your laminating machine. Our standard film selection includes laminating rolls between 3 Mil and 10 Mil in thickness. School film varieties are aptly named due to their popularity in the education market. This thermal laminate is 1.5 Mil, which is the most common thickness for K12 schools. School laminates will activate at 270 to 300 degrees, which is a common temperature range for roll laminating machines.
